  I have exact same problem with mine, along with rear main seal. Did all the seals with last timing belt. All I can say is my alternator will never rust!

  Well, well... I can't say I'd be happy about your oil leak, but it certainly
  makes it easier for me as I have suffered the _exact_ same problem for
  quite some time.

  Late 2006 I did more or less the same repair procedures you describe:
  - rebuilt cylinder heads
  - water pump/thermostat renewal
  - replaced timing belt + all rollers and adjustment damper
  - all oil seals including oil pump, crankshaft, cams etc.
  After 200-300 kms I noticed oil dripping down to the right side under the
  engine.
  Most probably the leak was there immediately after the rebuild as the oil
  tends
  to accumulate first on top of the engine undertray before it reaches the
  ground.
  The leak is not a huge one, but very disturbing. Additionally I have oil
  mist inside
  the timing covers. The leak seems to position itself to the right side of
  the engine,
  more engine oil on top of the alternator than on top of the hydraulic
  pump(none there).

  Fast forward to 2008: I have now taken the timing department apart for 4
  times in
  15 months to find the darn leak. I replaced the crank, oil pump and cam
  seals twice
  to make absolutely sure they aren't the ones leaking. I used a drill to turn
  the oil pump
  for 20 minutes to see that the oil pump seal is ok. I made pretty sure that
  all the lips
  of the new seals were not running on the tracks of the old seals and so on.
  Still dripping.
  (The problem with this engine is that you can't run it with both timing
  covers detached to
  really see what gives.)

  Before the head rebuild I had no oil inside the timing belt covers(some
  other leaks existed though),
  so something changed during rebuild - I've been chewing following thoughts:
  - head gasket leaking - I haven't checked, but I think there's a oil gallery
  running in the front at least
    in one head -> it could be worthwhile to re-tighten the head bolts a bit -
  on what basis or how much,
    I really don't know.
  - this may be over the top - too much oil left in i.e. cylinder head bolt
  threads in the block
    or elsewhere resulting in a cracked block. I do tend to clean all the
  not-thru-going threads in an
    alum. engine, but it's been a long time since I did the rebuild and cannot
  be sure anymore.

  Otherwise this drooling engine is running really well w/o any problems -
  have driven 10,000 mls
  marking territory everywhere - very nice...

  So, unfortunately I can't be of any help to you, but as my V8 serves as a
  winter car, the ABH will
  be lifted out this summer for further checks and full re-sealing. I will
  keep you posted, please do
  the same.

  P.S. Maybe this problem exists only in Scandinavia, eh...
